Imaging has become an essential tool in modern radiotherapy (RT), being used to plan dose
delivery prior to treatment and verify target position before and during treatment. Ultrasound …

In modern radiotherapy, verification of the treatment to ensure the target receives the
prescribed dose and normal tissues are optimally spared has become essential. Several …

Acoustic waves are induced via the thermoacoustic effect in objects exposed to a pulsed
beam of ionizing radiation. This phenomenon has interesting potential applications in both …

Objective. The goal is to increase the precision of radiation delivery during radiotherapy by
tracking the movements of the tumor and other surrounding normal tissues due to respiratory …

Proton radiotherapy favored over X-ray photon therapy due to its reduced radiation
exposure to surrounding healthy tissues, is highly dependent on the accurate positioning of …

The X-ray free-electron laser (XFEL) has remarkably advanced X-ray imaging technology
and enabled important scientific achievements. The XFEL's extremely high power, short …

Absorption based CT imaging has been an invaluable tool in medical diagnosis, biology
and materials science. However, CT requires a large set of projection data and high …

Photoacoustic imaging (PAI) is rapidly becoming established as a viable imaging modality
for small animal research, with promise of near-future human clinical translation. In this …

X-ray luminescence and X-ray fluorescence computed tomography (CT) are two emerging
technologies in X-ray imaging that provide functional and molecular imaging capability. Both …

Measuring the radiation dose reaching a patient's body is difficult. Here we report a
technique for the tomographic reconstruction of the location of photon pairs originating from …
